Virtual Advertising in Videos

For one of the hacks at A9/Amazon, I teamed up with one of my co-workers to insert ads into videos for brands. The idea was to identify spots in image frames where you can embed brand ads to present a seamless experience to the users. We used opencv, choose sample videos, used machine learning, color and shape detection algorithms to figure out spots in image frames which can be swapped out with banners of ads. After embedding ads into frames we re-composed back the video. For monetization, we proposed pay for play to the advertisers.

It was a lot of learning and hacking in one day. The crowd who looked at the hack were mesmerized with the idea. After the hack presentation, we found out that one of the judges, founded a start up with the same idea. It was a lot of learning and hacking in one day. A very memorable experience.

Excerpts from my older blog on internet archive

Using the power of web archive project, I was able to get content from my old blog, I used to publish in 2007-2008 time frame. You can see my previous blog here at http://web.archive.org/web/20080420212438/http://www.techiemusings.com/

Location aware Mobile Applications

May 10, 2008 at 8:16 pm · Filed under Uncategorized

We now have a OS on mobile phones exposing location as a attribute with Google’s Android. The practical applications are huge, the simplest being a poor man’s GPS if you combine with public Wifi’s. I did some research to see if there are any mobile browsers or mobile applications, exposing information about location of a user. Interestingly enough, I found information about twibble  a location aware mobile client, metosphere a mobile browser for Google Android.

Location Based Advertising

November 17, 2007 at 8:00 am · Filed under Uncategorized

I have been researching around to see the progress in the industry on location based advertising. I stumbled upon proximitymedia a contextual advertising firm which uses blue-tooth network to target content/ads to the user. Applications are end less. A customer gets lunch coupons, when a user enters mall during lunch time, sees movie trailers when he is waiting in a queue for tickets.

Content Recognition Software

November 15, 2007 at 7:07 am · Filed under Uncategorized

With the proliferation of peer to peer networks and youtube’s, I was researching to see, if I could find any software company which is cashing on copyright infrinngement detection. The software is definitely complex, given the scenario of multiple devices, mutliple wave formats and multiple encoding formats. A variation of fingerprints, hash signatures using Fast Fourier Transform are used to automate the detection of copyright infringement. Virage a division of Autonomy software is helping big name clients like BBC for detection of copyright infringement.

Social Ads and its hidden Implications

November 6, 2007 at 5:07 am · Filed under Uncategorized, Internet Advertising, Google

I was discussing about Social Ads from Facebook and its implications with one of the co-worker. In my previous post, I was ignoring one major advantage of a Social Network for advertisers, the “social effect”. If an advertiser is able to convert (acquire) at-least one user in a social network, the user can influence decision making of his close friends in the network and hence indirectly increase acquisitions for the advertiser. Google is doing all the right things to prevent Facebook from becomming the dominant Social Network. It would be interesting to follow the adoption of Social Ads across the web.

Social Ads from Facebook

November 2, 2007 at 5:34 am · Filed under Uncategorized

Facebook is throwing a direct challenge at Google by invading on its domain. It is all set to release “Social Ads” a platform for outside developers to develop niche applications to target ads to facebook users outside of network, based on cookies placed by facebook. This can be a game changing play from facebook, as profiles of facebook users is a rich source of information to target ads. That partly explains the lofty market cap Microsoft gave to Facebook. Google in-turn, has released Open Social platform to dilute the effect of Facebook social network. I am sure, Yahoo is going to make moves in this domain, as it is still the world’s most popular social network.

Peer to Peer Knowledge Management

November 1, 2007 at 5:18 am · Filed under Search

I was researching articles to know more about peer to peer networks. The recent propulsion of data transfer with an increase in youtube like sites has increased load on network. CDN’s are moving from centralized single point architectures to peer to peer nodes. This explains the recent vc funding into startups working on peer to peer cdn’s. Extending the concept, I was surprised to find the amount of research being done into peer to peer knowledge management. A direct take from one of the publications is “Of all the application domains we have studied, knowledge management is the one where the benefits of peer-to-peer and a clear and straightforward business model for suppliers are most evident”. By coupling virtual meta data of knowledge of all the nodes in a knowledge network and map of node to meta data, individudal data node can be a source of global information, making the node a better decision maker. The applications of such a framework are endless. The literature talks of knowledge management in a enterprise as a classic case

Direct Mail Targeting by Zillow

October 31, 2007 at 12:19 am · Filed under Internet Advertising

While, I was browsing through the web, I found an interesting article on how zillow is changing the game of direct mail marketing. The whole process started, sometime back in Sep 2006, when it allowed the users to add annotations to their home locations. Since, then now have more data about the adresses, and profiles of homes, zillow is selling this data to advertisers, which can then target the ads based on specific addess detail. Interesting concept. I wonder, if yahoo real estate would do anything in this space.

Story of Domain Names

October 30, 2007 at 10:09 pm · Filed under Java, Automated Domain Registration

Over the weekend, just for the sake of registering interesting domain names, I ran code to look for unregistered domains on yahoo domains with 3 or 4 alphabets using java httpclient. To my surprise, all the domains are allready taken. Though, I was expecting that domains with 3 alphabets being taken, but not with all the possible combinations of 4 alphabets. This effectively means, that 26*26*26*26 domains names are all ready taken. I was shocked. Yahoo with its 1.99$ domain registration deal seems to be the culprit. Another interesting conclusion, was the rate at which User Generated Content/Internet awareness is spreading over.

Silicon Valley Code Camp

October 30, 2007 at 5:31 am · Filed under Java, Microsoft

I attended/volunteered for the Silicon Vally Code camp over the weekend. It was a fun event. Had a chance to talk to Peter Kellner, Dave Wright. Dave Wright was confident that it is just the matter of time, before Live.com takes over Google. The technology sessions were really great. People were talking more about commodity computing/ondemand computing, a concept started by Sun Microsystems and now mass marketed by Amazon EC2/S3 services. It is getting traction with mainstream developers and is something definite to watch about. Dave Wright was commenting that Microsoft is not going to enter into it, unless it really starts kicking in. I was also amazed by number of people interested in knowing more about SilverLight. Adobe has to watch out. Though, I completely disagree, someone in session was evangelizing upon modifying architectures to use a cache/relational db in browsers to optimize load on servers. Another interesting session was GridGain a grid computing framework for Java. Overall, it was fun 2 days.

Integers Compression - Number Pairing

I ran into a problem where-in I wanted to persist multiple status codes into one integer for optimizing space. I thought about the problem more and ended up with potential solutions which could potentially leverage bit arithmetic of integers, but the solution was not generalized.

I eventually stumbled on this article on wiki http://en.wikipedia.org/wiki/Pairing_function which talked about a general mathematical function to represent multiple numbers using a single number. I could imaging applications of this approach in multiple scenarios such as caching sequences, compressing collections etc.
